Hi, on offers is six of these resin discs which measure 23 mm in diameter and are approximately 5 mm thick, they would be useful for making spacers for walking sticks, a little bit different.. Or jewellery or model making.. I acquired these with a job lot of buttons and so believe these are blanks for making the same, I am not 100 % sure what material they are, I think nylon or a resin, I had some slabs a while ago which looked similar. Anyway they are quitesolid and can be carved or drilled and look like they would polish up nicely..
I have them in quite a few different colours and cant get any more, when they are gone thats it..
Please do not hesitate to message if you have any questions.
